An auto-lock sealing valve structure of a rubber jointing ring in the containers using a lid attached to the rubber jointing ring

ABSTRACT

An auto-lock sealing valve structure of a rubber jointing ring using the lid attached to the rubber jointing ring includes a lid, a rubber jointing ring, and a bottle body. The rubber jointing ring connects the lid and the bottle body. The designation of the vapor escaping groove in the lid body helps the air inside the rubber jointing ring escape out, simultaneously the raised edge on the bottle lid prevents the rubber jointing ring part from coming out off. The gaps on the body part of the rubber jointing rings help the air inside the bottle body to entirely escape but still ensure that the liquid inside the devices cannot escape.

FIELD OF THE INVENTION

The present invention refers to rubber jointing rings having an auto-lock valve in the container products using a lid attached rubber jointing rings (hereinafter described in a particular product is a ceramic bottle having a lid attached rubber jointing rings).

BACKGROUND OF THE INVENTION

For a long time, a rubber jointing ring was an important material in various industries, it was considered as a protective tool to protect other articles to avoid impacts or undesirable events in the mechanical industry. The rubber jointing ring was used mostly in the electricity and water industry, the oil and gas industry, and the construction industry. Specifically, the rubber jointing ring was also used a lot in the medical and food industries. Effects of the rubber jointing ring are: firstly for use in water-proof, dustproof, sound isolation, and warm-keeping, secondly for use in filling between gaps, for increasing tightness and seals of the products. These are especially interested in the following products: food boxes, thermal cups, drink containers made of metals or ceramics, etc. However, the second effect of using rubber jointing rings for the above products has many drawbacks:

-   Firstly, the lid part and the body part of the product are not     entirely closed because the inside air did not escape ultimately,     resulting in a condition that the lid part is lifted while closed     for a while. -   Secondly, the jointing ring part separated from the lid part results     in a water-leaking state. -   Thirdly, the rubber jointing ring part separated from the lid part     results in that the inside liquid leaks along to the gap between the     jointing ring and the lid, then it sticks inside the gap so that it     is difficult to be cleaned up by the user. -   Fourthly, most products use rubber jointing rings to increase their     tightness and seals when containing the liquid at elevated     temperature (boiled water, hot tea, hot coffee, or other hot     drinks). After cooling, the lid part will stick tightly to the body     part so that it is difficult to open the lid. The inside air will     expand when pouring the liquid into the body part. After closing the     lid and cooling down the liquid, the inside air will shrink to     vacuum the inside air. As a result, the lid part sticks tightly to     the body part, so it will be difficult to release.

SUMMARY OF THE INVENTION

The object of the present invention is to overcome the drawbacks of the rubber jointing rings which are commercially available. To achieve the object mentioned above, the present invention provides a device containing the liquid made of ceramics using rubber jointing rings an auto-lock valve including:

-   1. The lid part     -   The lid is designed with the body part of the lid having 02         concave grooves that are opposite each other to help fit the         rubber jointing ring and the lid more easily because the inside         air of the jointing ring will escape through 02 concave points         mentioned above.     -   The sole part of the lid has a raised edge to help keep the         jointing ring part firmly attached to the lid (avoiding the         state that the jointing ring is released from the lid when         opening and closing the lid). -   2. The rubber jointing ring     -   The rubber jointing ring has 4 sealing layers:         -   The first layer is on the bottom, in the shape of flat             cylinder, to let only the air inside the bottle body escape             but still ensure that the liquid does not escape.         -   The 2nd and 3rd layers, which are designed in the cauldron             shape with gaps that are eccentric each other, are above the             first layer so that the air inside the container escapes             ultimately so that the lid part and the body part will be             entirely closed. Furthermore, these 2 layers are thicker and             stiffer than the first layer to keep the lid more firmly to             the body part of the container.         -   The top layer is immediately on the downside of the lid, and             it fills the gap between the lid and the opening of the             liquid container to increase its tightness and seals.         -   Layers of the rubber jointing ring are designed in the             cauldron shape according to different distances,             thicknesses, thinnesses to prevent the air inside the             container from escaping ultimately.         -   The rubber jointing ring is an integrated block to avoid the             liquid leaking, simultaneously removing the liquid sticking             on the gaps between the rubber jointing ring and the bottle             body causing unhygienic conditions in the use duration. -   3. A container     -   A container in the type of a bottle has the top part in the type         of a hopper with an opening part and the bottleneck in the type         of a cylinder and is successively bigger down to the bottle         body. The inside of the bottle’s neck is immediately beside the         opening designed in the V shape and having 2 concave edges. The         concave edges near the bottle opening are broader than the lower         concave edges.     -   The upper concave edges have dimensions suitable for inserting         the lid part with a rubber jointing ring into the inside without         any difficulty. The inside air escapes mainly from those concave         edges. -   4. The whole liquid container is made of ceramics to ensure the     hygiene and the safety of the container, do not create toxic     substances because of the direct contact with the liquid at the     elevated temperature during the storage progress, the use of the     liquid, keeping the inside liquid to be pure without loss or having     other odor impurities like other containers made of metals, plastic,     etc.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is described in detail according to the preferred embodiments based on the appended drawings, wherein:

FIG. 1 represents a liquid container with a closed lid including a lid 1, a rubber jointing ring 2 provided enclosing outside of the body part of the lid 1, a water bottle (a container) 3 is connected to the lid 1 by the rubber jointing ring 2. The rubber jointing ring 2 functions to prevent the liquid from overrun in the use duration, and simultaneously pushes the air inside the water bottle to escape during opening/closing the bottle lid.

FIGS. 2 a-d represents a lid, wherein FIG. 2 a is the front view, FIG. 2 b is the bottom view, FIG. 2 c is the plan view FIG. 2 d is the side view. As represented on the figures, the lid 1 has an outside rim 10 with a torus-shaped part, having a sphere cap-shaped peak summit curving up the and a leg 11 connected to the edge 12. On the outside rim 10 there are eccentric concave grooves 13 (represented more clearly on FIG. 5 ), the grooves 13 are slip resistant so that the manual handle of the lid 1 will be easier, the grooves preferably have a depth in a range from about 0.5 mm - 1 mm. The concave part 11 has a wall on the hopper with a diameter of the hopper leg that is less about 3-4 mm than the diameter of the outside rim 10. The concave part aids in manually handling the lid more easily upon opening and closing it, most preferably, the leg height L1 ranges from about 7-10 mm. If L1 is too long, it will be bulky. If it is too small, it will be unuseful. The edge 12 is in the torus shape with a cross-section radius of about 2-3 mm and the outer diameter D2 to be equal to the outer diameter D3 of the bottle opening, and this will ensure that the connection of the lid 1 and the bottle body 3 will be tight and sealed by the rubber jointing ring 2. The lid body 14 is in the circular cylinder shape extending downwardly. Two side surfaces of the lid body 14 have 02 vapor escaping grooves 15 provided central symmetry (represented more clearly on FIG. 8 ). The grooves 15 are suitably placed and have suitable dimensions so that upon inserting the rubber jointing ring 2 into the lid 1, a part of the grooves will be placed inside the rubber jointing ring. This placement will balance the vapor pressure inside the rubber jointing ring, avoiding the closed pressure phenomenon that will cause “vapor puffing,” making it difficult to insert the rubber jointing ring and the lid. However, if the dimensions of the grooves 15 are too big, the vapor can escape. As a result, the rubber jointing ring will be easily released from the lid. Most preferably, the grooves 15 have dimensions of Length x Width x Depth = 9 mm x 2 mm x 0.8 mm. The raised edge 16 is in the torus shape, having the outer diameter d1 that is longer of about 1-2 mm than the outer diameter d2 of the lid body 14. Therefore, the raised edge 28 of the rubber jointing ring is kept tightly to the lid body and does not come out off during opening, closing the bottle lid. Two small radial holes 17 are almost in the middle of the body 14, having a depth of about ½ cross-sectional radius of the body 14 for vapor escaping, expanding compensation upon heating the lid 1.

The inside of the rubber jointing ring 2 is the body part 22 in a hollow cylinder shape, and the outside has four sealing layers packing on each other in a specific interval. The jointing ring layer 21 on top is in the hopper shape with the expanding part upwardly. The outer rim diameter of the layer 21 equals the outer diameter D2 of the lid 1 and the outer diameter D3 of the bottle opening. This will ensure that the connection of the lid 1 and the bottle body 3 will be tight and sealed (avoiding impacts between a raised edge 16 of the lid 1 and the opening 30 of the bottle body 3). The body part 22 is in a cylinder shape, and the convex edge 23 has a diameter D5 that is longer of about 1-2 mm than the diameter of the body part 22. The edge 23 makes a border separating the cylinder body part 22 of the jointing ring 2 into two parts. An upper part 221 is thinner than the lower part 222. Therefore, the upper part 221 insertion into the lid 1 upon assembling becomes easier. The distance L3 is the height of the body part 22 from the bottom side of the layer 21 to a raised edge of the body part 22. The distance helps to pass fingers through so that assembling the rubber jointing ring 2 and the lid 1 becomes more effortless. Most preferably, L3>5 mm. The jointing ring layers 24 and 25 have the same structures and functions, with a flat upper surface and the cauldron-shaped bottom surface upwardly. On the body part of the jointing ring layers 24 and 25, there are 05 small gaps 27 provided regularly spaced and central symmetric, the interval between gaps is 15-17 mm. The gaps 27 above will help the air inside the bottle escape entirely upon assembling so that not cause the vapor barrier phenomenon when closing the lid. However, if the dimensions of these gaps are too big, the vapor will escape, causing the inside heat to be lost (in case the contained liquid at an elevated temperature), simultaneously these gaps will not close ultimately, resulting in the liquid leaking and the bottle lid will come out easier off the water bottle. Most preferably: these gaps 27 have an opening width of about 0.5-1 mm. Two side walls of the radial gap make a gap successively narrower toward the central point of the cylinder. The gaps 27 are provided uneccentrically and alternatingly in the jointing ring layers 24 and 25, 26. This helps the inside air to not escape together in the same direction. This also helps keep the liquid in the layer 24 if it leaks through the layer 25 and the layer 26. The layer 26 is in a circular cylinder shape with the flat upper and bottom surfaces. This layer lets only the inside air pass through and prevents the liquid from overrunning to the outside. The outer rim diameter of the layers 24, 25, 26 (d4, d5, d3) successively reduces from up to bottom, corresponding to the bottle’s neck diameter that equals the closing level of the lid. The raised edge 28 of the jointing ring has the flat top and bottom surfaces, and the body part in the middle of the edge that was rounded with its diameter longer than the outer diameter of the raised edge 23 of the lid. Therefore, the raised edge 28 entirely enclosures the raised edge 23. The hollow inside 29 and the raised edge 28 have shapes and dimensions D1, L2 provided adaptable to dimensions d1, 12 of the lid 1. Thus, the body part 14 and the raised edge 16 of the lid 1 fit in the inside of the rubber jointing ring 2. Most preferably, d1, d2 are longer of about 0.5-1 mm than D1, D2 (because the rubber jointing ring is elastic, so that d1, d2, which are longer than D1, D2, help keep the rubber jointing ring more firmly to the cap). The rubber jointing ring is made based on the following ratio:

-   The outer boundary perimeter of the rim 24 when has not been     inserted: c4 = d4 x 3.14 -   The outer boundary perimeter of the rim 24 when has been inserted     (the perimeter of the container opening at the position of the     inserted sealing rim 24): C4 = D4 x 3.14 -   The width of the groove opening/gap -   L7 = (c4-C4)/n -   n: number of grooves -   depth of grooves -   L8 = [(d4-D4)/2] x 1.5

Container 3 is in the shape of an upside-down hopper with an opening part and a bottle’s neck which is substantially cylinder and is successively bigger down to the bottle body. The inside of the bottle opening 30 and the concave edge 31 (protruded toward the inside) are in shape and dimensions D3, L3, D4, L4 provided adaptable to dimensions d3, 13, d4, 14 on the rubber jointing ring 2. Therefore, the bottom part 28 and the layers 24, 25, and 26 of the rubber jointing ring fit inside the bottle opening 30 and the concave edge 31. Most preferably, d3, d4 are longer of about 0.5-1 mm than D3, D4. The concave edge 31 helps keep the bottom part 28 of the rubber jointing ring 2. Most preferably, the concave edge 31 has dimensions of Width x Depth = 2 mm x 0.8 mm.

More particularly, the bottle opening and the bottle’s neck are structured with two interconnected hollow parts K1 and K2. The hollow part K1 on top directly contacts the container opening in the cylinder shape with a diameter D4 at the largest-cross-section position corresponding to the position of the layer 24 upon assembling; the upper opening D4.1 has a diameter that is slightly smaller than D4. The hollow part K2 is in the hollow torus shape having a diameter D3 at the largest-cross-section position corresponding to the position of the layer 26 upon assembling; the intersection line of the two hollow parts K1 and K2 is rounded to have a diameter D5 corresponding to the position of the layer 25 upon assembling. Dimensions D3, D4, D5 are in the order D5 <D3 <D4. I <D4. This dimensional relationship helps fit the lid and the jointing ring into the bottle opening more easily. In general, the diameter of the bottle opening tends to narrow/reduce from up to bottom. However, based on the dimensional conversion, there is a localized dimensional difference between these parts: D4>D4.1; D3>D5 in a position for assembling sealing layers so that sealing layers 21, 24, 25, 26 lean on walls, respectively, on the bottle opening. The bottle’s neck is in two opposite directions making an auto-lock structure both to seal and to auto-loose the lid 1.

Operation Principle

To contain the liquid in a ceramic bottle is based on a principle using a rubber jointing ring with an auto-lock valve, particularly:

-   Step 1: To assemble the rubber jointing ring part 2 to the lid 1.     The bottom part of the lid 1 must contact the sole part of the     rubber jointing ring 2, and the top layer 21 of the rubber jointing     ring 2 contacts the bottom surface of the raised edge 12 on the lid.     When assembling, the air inside the rubber jointing ring 2 passes     through two vapor escaping grooves 15 of the lid body to go to the     outside to be more easily assembled. The raised edge 16 on the lid     is entirely inside the sole part 28 of the rubber jointing ring 2 so     it is difficult for the rubber jointing ring to come out of the lid. -   Step 2: To put the liquid into the container, the liquid contained     inside may be much or less depending on the user’s need. -   Step 3: To use the lid 1 attached to the rubber jointing ring 2 to     connect to the water bottle. When closing the lid, the air inside     the bottle escapes through the gap 27 on the layers of the rubber     jointing ring 2 to go outside. After the air escapes to the outside,     the rubber jointing ring will gradually close the gap 27 when     inserting the lid deeply into the water bottle. Thus, the rubber     jointing ring’s auto-lock valve structure lets only the air escape.     Therefore, the opening and closing of the lid become more easily.     Simultaneously, it prevents the inside liquid from escaping.

Utility: The auto-lock valve principle of the rubber jointing ring includes all of the following conveniences:

-   It may be used for all products using rubber jointing rings. -   The production cost of the rubber jointing ring according to the     above principle is low, given a high economic effect. -   The shape of the rubber jointing ring is designed in a monobloc with     an excellent aesthetic. -   The rubber jointing ring is designed in a monobloc so that overcome     thoroughly drawbacks: The rubber jointing ring part separated from     the lid part results in that the inside liquid leaks along to the     gap between the jointing ring and the lid, then it sticks inside the     gap so that it is difficult to be cleaned up by the user.     Simultaneously, the parts jointed by the rubber jointing ring will     increase their tightness and seal because the inside air escaped out     completely. -   The present invention has simple usage, easy implementation, and     convenience for all applications.
